Can a Nonsymmetric Metric mimic NCQFT in $e^{+} e^{-} \to γ γ$ ?

Nick Kersting, Yong-Liang Ma

In the nonsymmetric gravitational theory (NGT) the space-time metric $g_{μν}$ departs from the flat-space Minkowski form $η_{μν}$ such that it is no longer symmetric, $i . e .$ $g_{μν…

Extracting Event Dynamics from Event-by-Event Analysis

Jinghua Fu, Lianshou Liu

The problem of eliminating the statistical fluctuations and extracting the event dynamics from event-by-event analysis is discussed. New moments $G_{p}$ (for continuous distribution)…

1/m_Q order contributions to B \to πl νdecay in HQEFT

W. Y. Wang, Y. L. Wu, M. Zhong

Contributions to B\to πl νdecay from 1/m_Q order corrections are analyzed in the heavy quark effective field theory (HQEFT) of QCD. Transition wave functions of 1/m_Q order are cal…

Nonsymmetric Gravity and Noncommutative Signals

N. Kersting, Y. L. Ma

Models in which the space-time metric $g_{μν}$ is not symmetric, $i . e .$ $g_{μν} \neq = g_{ν μ}$ may make predictions in scattering experiments, for example in a future $e^{+} e^{-}$ linear…

HQEFT as A Large Component QCD and Comments on The Incompleteness of HQET

Y. L. Wu, Y. A. Yan, M. Zhong +2

The Heavy quark effective field theory (HQEFT) is revisited in a more intuitive way. It is shown that HQEFT is a consistent large component QCD of heavy quarks. In the non-relativi…

Nonstrange hybrid compact stars with color superconducting matter

Igor Shovkovy, Matthias Hanauske, Mei Huang

Realistic nonstrange hybrid compact stars with color superconducting quark matter in their interior are constructed. It is shown that a positively charged two-flavor color supercon…

Trilepton + top signal from chargino-neutralino decays of MSSM charged Higgs bosons at the LHC

M. Bisset, F. Moortgat, S. Moretti

We perform for the Large Hadron Collider (LHC) a detailed study of charged Higgs boson production via the top-bottom quark associated mode followed by decays into a chargino and a…

Testing anomalous gauge couplings of the Higgs boson via weak-boson scatterings at the LHC

Bin Zhang, Yu-Ping Kuang, Hong-Jian He +1

We propose a sensitive way to test the anomalous HVV couplings (V=W(+/-),Z(0)) of the Higgs boson (H), which can arise from either the dimension-3 effective operator in a nonlinear…

Gauge and Lorentz Covariant Quark Propagator in an Arbitrary Gluon Field

Yong-Hong An, Hua Yang, Qing Wang

The quark propagator in presence of an arbitrary gluon field is calculated gauge and Lorentz covariantly order by order in terms of powers of gluon field and its derivatives. The r…

Anomalous Action in Gauge Invariant, Nonlocal, Dynamical Quark Model

Yong-Liang Ma, Qing Wang

Anomalous sector of chiral Lagrangian is calculated in a gauge invariant, nonlocal, dynamical quark model. The Wess-Zumino term is proved coming from two kinds of sources, one is i…
